Features of the Electronic Ignition Systems, items # EIS-N135, EIS-N200, EIS-350, EIS-N720, EIS-P200, EIS-P350  (please see related article for BTU and inlet/outlet sizes).

These are "pilot on demand" ignition systems that feature flame rectification with solid-state logic and flame sensing.  These systems offer the same general features and requirements (in no particular order):

1) Must be located outside of and adjacent to the fireplace where 120-volt electricity and gas can be installed.  Please see attachments "EIS Install rqmnts.pdf" and "
EIS.Typical.Install.pdf" for further information.

2) Electricity is stepped down to 24-volt with the supplied transformer.

3) The maximum length of the pilot and electrode leads is 72-inches.  We recommend that the distance from the location of the control module to the location of the pilot assembly for the burner be no more that 60-inches.  (We do not have a source for longer leads, and the component manufacturer does not recommend using longer leads, as this decreases the spark's intensity).

4) Operation is ON/OFF (no flame modulation), so a manual valve (such as our V17 (up to 100,000 BTU/hour) or V1 or V2 (up to 200,000 BTU/hour)) is needed to be installed between the burner and the control valve in order to adjust the flame height.  You will need to source a larger capacity valve for the large EIS kits.

5) The operation sequence is the same for all of these units.  Please refer to the attachment at "EIS operation sequence.pdf"

6) The flame rectification is achieved by the pilot flame remaining steady on the sensor electrode throughout the entire time the unit is ON.  If the pilot flame pulls off of the sensor (from influences created by the flame, draft or wind), the unit will stop the flow of gas to the main burner, and commence a relighting sequence.  Mitigating this condition may be accomplished by an adjustment to the sensor electrode, or by repositioning or shielding of the pilot/sensor assembly.  

7) Because of #5 above, these systems are not recommended for use out of doors, especially in open, multi-sided applications where the elements could influence the system from any direction.  Be prepared for call-backs if these systems are used in outdoor fire pits.

8) These systems can be operated with a wired wall switch, remote ON/OFF control (such as our SR-MV1), or Home Automation System (Lutron, Questron, etc.).

9) These systems may be used with an Exhausto-type power vent or other type of interlock system.  See the attachment "EIS Instructions A.pdf" for wiring instructions.

10) An HVAC contractor is the best tradesperson to coordinate the installation of the system.  These systems are furnace controls that are adapted to the fireplace.  The HVAC technician has both the electrical and plumbing skill sets required to install and service these systems.
